Abstract
The Canadian Forces (CF) is seeking to establish permanent and temporary operational support hubs at strategic locations around the globe to improve its logistics support effectiveness and responsiveness for deployed operations. This paper addresses two logistics problems associated with the hub-based support concept, namely, hub location optimization and aircraft routing problems. A discrete facility location model was developed to analyse the hub-based support effectiveness and to determine the optimal hub locations. An aircraft routing model was also developed to determine optimal aircraft routes for the movement of cargo and supplies from various support hubs to a theatre of operation. Both models were formulated using mixed integer nonlinear programming. Historical CF deployment and sustainment data were used to conduct the analysis and to illustrate the methodology. The study indicates that the hub-based support approach would offer potential cost avoidance on sustainment lift and could be an effective strategy for improvement of the CF's support capability. It also indicates that potential lift costs could be avoided through optimal routing of sustainment flights.
